［摘要］京張高鐵清河站采用建橋合一結(jié)構(gòu)體系，有兩條國(guó)鐵正線通過。A區(qū)主站房為復(fù)雜高層組合結(jié)構(gòu)，地下結(jié)構(gòu)無(wú)縫超長(zhǎng)，長(zhǎng)度為660m；站廳層采用鋼框架結(jié)構(gòu)，屋蓋結(jié)構(gòu)采用焊接H型鋼桁架結(jié)構(gòu)，屋面最大跨度84m，最大懸挑18m，由巨型A柱、Y柱、直柱混合支承。B，C區(qū)地鐵區(qū)間上方為地下車庫(kù)，存在托柱轉(zhuǎn)換。京張高鐵清河站結(jié)構(gòu)設(shè)計(jì)的難點(diǎn)較多，為此開展了多項(xiàng)研究：如建橋合一結(jié)構(gòu)體系的抗震性能研究，考慮土-結(jié)構(gòu)共同作用的地下結(jié)構(gòu)的抗震分析，A區(qū)結(jié)構(gòu)的風(fēng)荷載取值研究，大跨屋蓋采用A柱、Y柱、直柱混合支承結(jié)構(gòu)的抗連續(xù)倒塌性能研究，高鐵候車廳的樓面振動(dòng)舒適度研究，重要節(jié)點(diǎn)的補(bǔ)充分析，綠建設(shè)計(jì)及結(jié)構(gòu)健康監(jiān)測(cè)系統(tǒng)設(shè)計(jì)，通過各項(xiàng)研究論證了結(jié)構(gòu)的安全性、合理性、經(jīng)濟(jì)性。

Abstract:Qinghe Station of Beijing-Zhangjiakou high-speed railway adopts the structural system of building-bridge integration, and has two main national railway lines passing through. The main station building in area A is a complex high-rise composite structure with seamless and super long underground structure of 660 meters. The station hall floor adopts steel frame structure, and the roof structure adopts welded H-shaped steel truss structure. The maximum roof span is 84 meters and the maximum overhanging is 18 meters, which is supported by a mixture of A column, Y column and straight column. The underground garage is located above the subway section of area B and area C, with support column conversion. There are many difficulties in structural design of Qinghe station of Beijing-Zhangjiakou high-speed railway, so many researches had been carried out, such as the research on seismic performance for system of building-bridge integration, the seismic analysis of underground structure considering soil structure interaction, the wind load value for structure of area A, the progressive collapse resistance of long-span roof structure supported by a mixture of A column, Y column and straight column, the floor vibration comfort of high-speed railway waiting hall, and the supplementary analysis of important joints. The green building design and structural health monitoring system design were introduced too. The safety, rationality and economic usefulness of the structure are demonstrated through various design studies.

Keywords:Qinghe Station Beijing-Zhangjiakou high-speed railway;building-bridge integration;progressive collapse resistance;vibration comfort degree;super long structure
